WELT-GUIDE.

SPECIFICATION lforming part of Letters Patent No. 610,323, dated September 6, 1898.

Application filed Junevll, 1897.

To all whom t may concern:

Be it known that I, WILFRED JOHN DREY, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful VVelt-Guide, of which the following is a specification, reference being had to the accompanying drawings.

The present inventionrelates to sewingmachines for sewing the welt to the under side and upper of a boot or shoe, and more particularly to an improved welt-guide for use in such machines.

The object of the present invention is to guide a channeled welt to the stitch-forining mechanism of the machine and to so arrange said welt-guide that it will gradually open and turn up the channel lip or iiap of the welt in such position that as said welt emerges from the welt-guide the channel lip or iiap will be raised up to open the channel, so that the stitches of the inseam may be placed in such channel.

To the above end the present invention relates to the devices and combinations of devices which will be hereinafter described and claimed.

The present invention is illustrated in the accompanying drawings, in Which- Figure l is a plan showing my new weltguide and a portion of a shoe. Fig. 2 is al view of the under side, partly broken away. Fig. 3 is a section on line 3 3 of Fig. 1, showing also the needle of the sewing-machine. Fig. et is an edge view. Fig. 5 is a like view to Fig. 2 of a modified form. Fig. 6 is a sec-- tion on line G 6 of Fig. 5, looking in the direction indicated by the arrow. Fig. 7 is a section on line 7 7 of Fig. 5. Fig. 8 is a view of the under side, showing another feature of my invention. Fig. 9 is a section on line 9 9 of Fig. 8.

In Figs. 1 to 4 I have shown the simplest form of my invention. In this form the weltguide is the same in its construction as the ordinary welt-guide, except that it is provided with the lip-turner d, fastened to or integral with the body of the guide. This lipturner is shaped like a plowshare, being nearly parallel with the body of the guide at one end and rising gradually until it is nearly perpendicularto the body of the guide at the other.

The shape of the lip-turner d serves to turn seria No. 640,280. [No man.)

the lip b of the channel h in the welt B back, so that when the welt emerges from the guide the lip b will be held almost perpendicular to the surface of the welt and allow the needle dto enter the welt at the bottom of the channel, as will be clear from Fig. 3.

I am aware that a projection on the body of the welt-guide to cause the welt to bend is old and well known, but I am the iirst, so far as I know, to provide a welt-guide with a projection adapted by its shape to turn back the lip of a channel in. the welt, and this is the main feature of my invention.

It sometimes happens that the channel or the welt is deeper at one place than at another, and in order to have the lip-turner follow these irregularities in the channel I make the lip-turner as shown in Figs. 5 to 7. In these gures the lip-turner is made in two parts e e', which are normally in line and form together a lip shaped similarly to the lip-turner a of Figs. l to 4. The part e of this lip-turner is fast to the body of the welt-guide, while the part e is mounted in a slide c2, which slides in a groove cut in the body of the weltguide. The leafsprin g g, one end of which is secured to the body of the guide at g' and whose other end ts into a transverse slot e3 in the slide e2, allows the part e of the lip-turner to move in and out as the irregularities in the depth of the channel occur, and the inward motion of part c is limited by screw e4, screwed into the end of slide e2, the end of which is arranged to engage a fixed portion of the weltguide, and this construction of the lip-turner in two sections, one of which is fast to the body of the guide and the other is free to move in and out, is another feature of my in vention.

In Figs. 8 and 9 I have shown another feature of my invention. In these figures the shield f, which coniines the welt in the guide, is hinged to the body of the guide at f. The screw f2, whose head is partly cut away, serves to hold the shield f closed, and by turning the screw until the vcut-away portion of the head comes over the' shield the operator is enabled to open the shield and lay the welt in place on the guide. This feature of my invention is one of great practical importance when my channeled welt is used, as the constructionv of the lip-turner and the channel on thewelt renders it extremely difticult to a slide. carrying the movable part, a spring 15 acting upon said slide and an adjustable stop to limit the movementI of said slide in one direction, substantially as described.

4. A Welt guide provided With a shield hinged to said guide at its outer end to swing in a plane at right angles to the plane of the guide, and means to hold the shield closed, substantially as described.
